2oz (60ml) Cl Boston Rnd w/ 20-400 Blk Phenolic P

Clear Glass Boston Round Bottles offer maximum visibility and sample integrity. These general use bottles are perfect for liquids, product storage, and field or plant sampling projects. They feature a round body, rounded shoulders and narrow screw neck opening. These environmentally sensitive bottles help eliminate waste and help to insure product integrity for long term storage.

Attached black phenolic (thermoset) caps with PolyCone liners form an exceptionally tight seal and offer a good chemical barrier. This liner molds itself around the sealing areas of the finish as the cap is screwed on, virtually eliminating leakage, evaporation, contamination, binding and backing off. Great for everything from liquids, to soaps, to macro-invertebrates.
